| 摘 要： | 在分析反应堆松动部件冲击信号噪声基本特征基础上，利用小波非线性圃值滤波方法对冲击信号的提取进行了研究。结果表明：利用小波非线性阈值滤波方法能较好地检测在随机噪声下的冲击信号，并能保持信号的波形基本不变。

| Abstract: | On the basis of analyzing the basic features of impact signal noise from reactor loose parts, the wavelet nonlinear threshold value filtering method for the use of impact signal extraction is studied. The results show that this method can detect impact signal and keep up signal wave form basically immovableness. |
